Upper heater vents e93
Hi guys, hope your all well.
Have a slight issue where the centre vents blow out hot a lot of the time. Even though the slider is set to cold. Sometimes I have to stick the air con on then it starts to blow cold. I can then turn air con off and it stays blowing cool. Is the upper vent controlled electronically by itself or does the final stage resistor control everything. |
